1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)-urea when ingested by the last two larval instars of the spruce budworm, Choristoneura fumiferana, inhibits cuticle development leading to morphogenetic deformities in the pupal stage. Laboratory and greenhouse studies indicate that this material could be used to control natural populations of spruce budworm.

Résumé

L’ingestion de 1-(4-chlorophenyl)-3-(2,6-difluorobenzoyl)-urée par la Tordeuse des bourgeons de l’Epinette (Choristoneura fumiferana) aux deux derniers stades larvaires, inhibe le développement cuticulaire qui détermine les difformités morphogénétiques à la nymphose. Des études effectuées au laboratoire et sous serre montrent que cette substance pourrait servir à la régulation des populations naturelles de la Tordeuse des bourgeons de l’Epinette.
